I am between 5'11 and 6' and i weight around 180 lbs. I have some excess fat in my breast? area(dont even know what to call it) and my stomach. I want to lose this fat and maybe gain some muscle while i'm at it. I work at FedEx where I load trucks and I do a lot of work and lift a lot. On my days off I do about 50 sit-ups and I curl some weights. Or well this is what i'm starting to do. What kind of excercises would allow me to lose this fat? Also, what kind of foods should I be eating??
